Snow Watch Winter 2010/11 - Leg 1 Update and new Leg 2

Well this season has got off with back to back legs.

Leg 1 Update

This was the snow that was due today. The warnings were quickly downgraded over the last couple of days and in the end we just got a "shake" of snow overnight. For non snow watch regulars a shake is what you would get if you get an icing sugar duster and give it a shake. It has already almost vanished. Judging by the cloud cover although snow like, it does not have that heavy pregnant look so it seems that is pretty much the end of leg 1.

1254 hours: Very slight flakes in the air

Leg 2 - Blizzard Watch

Yes, you heard it right the met office put out an early warning for Tuesday yesterday with a chance of blizzards:

Rain is expected to spread northwards during the day, turning to snow widely as it does so. Strong northeasterly winds will also be a feature, perhaps reaching gale force in exposed areas. This will lead to the potential for blizzard conditions in places, with significant disruption a possibility. At present, these conditions seem likely to continue into Wednesday.

This is expected to cover the whole of the south of England. A couple of technical weather points for you. Snow usually comes down from the north, when it comes from the south it turns from rain to snow as it moves to the north. In addition if the new low pressure overwhelms the cold high pressure (already in place) then it may warm up increasing the likelihood of rain. Basically for the best snow fall you want to be on the cold side of the pressure battleground giving maximum snow. Of course if it is cold enough and the pressures are finally balanced you also get a heavy snow fall.

So snow could be on the way up from the south but it may fall as rain, or fall as rain first. Only updates from the met office will give us a better idea of what is going to happen.

For a bit of fun, here is an artist's impression of me standing in a blizzard. If you look very closely you can see me waving.

Of course while I have been writing this article the met office have given their daily update, blizzards has been changed to heavy and drifting snow on Tuesday for the east and not the south of England. The good news is that I am still due to get some.





Latest met office update is:

There is a moderate risk of severe weather affecting northern and eastern parts of the UK. Strong north-easterly winds and heavy snow showers will lead to accumulations of 5 to 10cm quite widely and up to 20cm in places. There may also be some drifting of snow in the wind.

More analysis and news from North Oxfordshire Snow watch in due course.
